The test suite fails in numerous places with anydbm and sqlite backends.
Some failures are caused by string path comparisons (e.g. /tmp vs c:\tmp).
Others are because the test suite or code doesn't close open database files.
So deleting the roundup tree or clearing the database fails because you can't
delete open files on windows. Also test_liveserver.py is missing some guards
that prevent tests that require the requests modules from running if it can't
be imported.

Probably more issues as well, but this what I have so far.
